Physical modeling of the long-term behavior of integral abutment bridge backfill reinforced with tire-rubber

Abstract The primary objective of this study is to investigate the benefits of adding tire rubber as an inclusion to backfill behind integral bridge abutments. In this respect, four physical model tests that enable cyclic loading of the backfill-abutment are conducted and evaluated. Each test consis...
